Harness Power reviews
• last updated FEB 26, 2026Loading map...
The Verdict
Harness Power went out of business in 2023 and abandoned hundreds of customers mid-project. We analyzed more than a hundred reviews and found a company that routinely failed inspections, left systems nonfunctional for months, and then shut down without notice, leaving homeowners with $70,000 loans for useless panels on their roofs. One customer reported panels installed in July 2022 that still weren't working by February 2023 after repeated failed inspections. Another discovered 25 roof tiles simply weren't replaced after installation, leading to interior leaks that Harness refused to repair. The company also failed to pay subcontractors, triggering mechanic's liens against customer properties even after homeowners had paid in full. Communication was a disaster across the board. We found 53 mentions of unresponsive staff, broken promises to send specialists, and customer service reps who would say "we'll get right back to you" and then disappear for weeks. The 21 positive reviews all predate mid-2022, before the operational collapse became obvious.
If you're researching Harness Power because you found old marketing materials or a dormant listing, stop. The company is defunct. Any panels they installed come with worthless warranties and no support infrastructure. Look elsewhere.
Reviews That Shaped Our Verdict
Sarah G. had a residential solar system installed in November 2022 and was cleared to turn it on in December. By early February she received notice that a mechanic’s lien had been recorded against her property because the installer hadn’t paid a subcontractor. She contacted the company immediately; they asked for 48 hours to review the account and promised to respond, but a week passed with no word. When she called again, the representative requested documents, which she provided within 15 minutes, and then the company went silent once more — three days of follow-up produced no response. She discovered the subcontractor could foreclose on the house based on that lien even though the company had taken cash in full at installation. The most striking detail: despite prompt payment from her side, the project’s unpaid subcontractor left a recorded lien that the installer did not resolve or even acknowledge after repeated contacts, putting the home’s title at risk.
Stephanie F. began a solar installation a year ago and ended up tangled in delays, failed inspections, and a company collapse. She bought a system that didn’t perform as promised, then spent months pushing the installer to fix problems and respond to questions. The crew mounted the panels in July 2022, but the first inspection didn’t happen until November because parts had to be swapped. That inspection failed, and the installer then spent about three months reworking plans to meet the city’s requirements. An inspection was set for last week but was postponed by rain — and then, on Friday, customers discovered the company had gone out of business without notifying them. Now she faces more than $70,000 in loan debt with payments starting in July, while nonworking panels sit on her roof and she scrambles to get the inspection completed and the system activated. She’s hopeful the project can be finished but is unsure about legal options; the hard, memorable fact is this: loan payments will begin before the system is even approved to run.
Hilary C. signed a contract on 10/26/2021 for an oversized solar array and a battery on her home — sized up so she could eventually power an EV and, she was told, “live off the grid” during peak hours. The crew finished the physical install on 12/28/2021, but what followed felt like a yearlong exercise in fixes, missed promises, and poor communication. She watched inspectors make five or six trips before the job finally passed, then waited months for permission to operate (PTO), which only arrived on 6/29/2022. The company emailed a sketchy how-to with pictures that weren’t even of her system after promising an in-person activation; she followed the directions and the system stayed dead. A technician arrived at the end of August and recommended swapping to a different set of equipment the company claimed to “know well,” promising an un-install and re-install in about two weeks. Before committing, she asked for specifications and a cost breakdown — none ever arrived. By October installers returned without the battery; the battery finally showed up in November and also failed to work. The company blamed improper wiring (wiring the crew had installed) and said a specialist was needed.

What You Can Expect
Marlen bought a rooftop solar system in 2019, paid $10,000 up front and was promised a lifetime warranty. When the panels stopped producing in September 2023, they called the service number expecting support and discovered an automated menu that steered callers to unrelated services — lifeline callers, addiction specialists, pest control, Dish Internet and car insurance — instead of any solar help. They learned the system was originally installed by Larsun, which had been acquired by Harness Power, but Harness Power now appears to be closed out for business, leaving no clear successor to honor the warranty. After hitting that dead end, they ended up with a nonfunctional array, a claimed lifetime warranty that they cannot access, and no obvious way to get the $10,000 investment serviced.
